Ram Blowout Preventer Application The ram BOP is designed to seal off the tubular annulus or the well. With the ram BOP in the closed position, such operation as circulating drilling fluid, re-leasing pressure and killing the well can be special circumstances; the ram BOP can shear the pipe in the hole to seal off the well. if the ram BOP has variable bore rams ,it can seal off the annular space between the casing and pipes whose sizes are at the mini-mum and maximum of the ram’s range. Ram Blowout Preventer Structural Features Body Structure Shape. The BOP has a body similar to square shape, having a vertical bore through which the pipes can pass and ram cavities in which the rams move in the horizontal direction Connection types. The BOP are offered with studded, flanged and hubbed top and bottom connections. The sizes of flanges, bolts, clamps and ring grooves all conform to API 16A Ram structure For dualface ram, the upper face and lower face of the ram are exactly symmetrical. Various drilling tools with different sizes in only necessary to replace the semi-annular rubber sealing ring and ram compact, the others can be interchanged; Seal of Ram The seal of the ram putting into effect of the packing wellhead must depend on four seals. i.e. the seal between the top of ram and housing, the seal between the fore-end of the ram and the pipe -line, the seal between the housing and the side-gate and the seal between piston rod and the side-gate. Looking Mechanism of Ram The manual locking device depends on manpower to rotate handwheel to close or lock the rams. It shall be noted that the manual locking device only can be used to close rams. Be sure to make the manual locking device return to the original position to unlock the rams before opening the rams with hydraulic pressure. Blowout Parts
